Description

TECHNICAL FIELD

[0001] The utility model relates to product cooling technical field, specifically, relate to the quickening cooling device of extrusion product. BACKGROUND

[0002] The current aluminum alloy extrusion product's early cooling depends on artificial connection water pipe, and the surface of discharge is carried out water spray cooling. However, artificial operation has many limitations: for the product with thick wall thickness and large diameter, it is difficult to realize timely and complete cooling.

[0003] Aluminum extrusion product is sensitive to cooling process, especially high-performance and high-hardness products, when the surface is cooled only by small water pipe, the center part of the product cannot achieve instantaneous cooling effect, which seriously affects the quality of the product. At the same time, artificial operation cannot build a cooling cycle system, and the cooling water is directly discharged after one-time use, which not only causes a large amount of water resource waste, but also cannot filter and clean the aluminum scraps and other impurities mixed in the cooling water due to the lack of circulation purification mechanism, so that the impurities are easy to adhere to the surface of the product in subsequent cooling operation, further affecting the product quality, and also cannot realize continuous and stable cooling through recycling water body, reducing the cooling efficiency.

[0004] In addition, artificial operation needs to be repeated with product replacement, which is low in efficiency; the outlet temperature of extrusion product often reaches 500 DEG C or above, and workers near the discharge port have the risk of scalding; and the water pressure of ordinary water pipe completely depends on manual control, which cannot meet the water pressure requirement of product instantaneous cooling.

The stepped structure inside the tank, in conjunction with the filter plates, intercepts and retains impurities of different sizes on their respective plates, achieving efficient layered filtration. The filtered water is then stored in the collection chamber, completing the water circulation process. This ensures both cooling effectiveness and water conservation. The tank's interior is equipped with several fixed plates, each with a guide plate on one side of its top. At the bottom and on one side of the fixed plate, there is a filter plate that cooperates with the impurity cleaning component. The inner cavity of the water tank has a stepped structure.

A water collection chamber that communicates with the bottom of the water tank is set on one side of the water pump. The water pump and the water collection chamber are connected by a pipe.

The top of the first water spray nozzle has a first connecting pipe that communicates with the first baffle. Several second connecting pipes are arranged through the outer circumference of the first baffle. Several third connecting pipes are arranged at one end of the cooling nozzle.

[0011] Further, in order to drive the gear and rack structure by the servo motor, the transmission of the gear and rack will drive the brush to move stably along the filter plate, and in the moving process, the brush can gradually push the impurities accumulated on the upper filter plate to the bottom filter plate, thereby realizing the centralized cleaning of the impurities, and further reducing the frequency of manual cleaning, effectively avoiding the problem of impurity accumulation and blocking the filter plate, affecting the filtering effect, and further improving the stability and continuity of the whole device operation.
